I have noticed that whenever I like a website or page and include a comment, nothing shows up in my newsfeed and I can't see the like at all. Is this an error with the site or something wrong with my Facebook account?

Unfortunately, this question appears to be off-topic because it is about a third-party website. Questions here are expected to be in relationship to your own website. You might ask this over at Web Applications however, but be sure to search their questions and read their FAQ first.
